Is Veo 3.1 cheaper than Omni Flash for 8-second clips?

Yes. At 720p/1080p, Veo 3.1 Fast costs a flat $0.75 per generation (8s fixed), while Omni Flash at 8s 720p costs ~$0.83. At 1080p, Veo stays $0.75 while Omni Flash rises to ~$1.25. However, Omni Flash offers 4K, conversational editing, and multimodal inputs that Veo does not.

Does Veo 3.1 support conversational editing like Omni Flash?

No. Veo 3.1 generates clips independently. Omni Flash supports conversational editing, where you can iteratively refine a generated clip while the model preserves scene state across iterations.

Which model has better motion quality: Veo 3.1 or Omni Flash?

Veo 3.1 Fast currently leads in pure motion coherence, object permanence, and physics realism. Omni Flash is excellent but optimized more for multimodal flexibility and editing workflows than for topping raw motion benchmarks.
